Abstract: 841,837. Television. RANK CINTEL Ltd. Oct. 31, 1957 [Oct. 31, 1956], No. 33234/56. Class 40(3). In a subscription television system in which signals generated by a camera 1 (Fig. 1) are supplied to the transmitter 6 via a coding device 4 which, under the control of a device 7, periodically changes the "mode" of transmission in any desired manner so that a satisfactory picture cannot be reproduced by unauthorized receivers (i.e. receivers not equipped with appropriate decoding apparatus) de-coding of the signals received by authorized receivers, so as to reproduce a satisfactory picture, is controlled by means of signals generated at each change of "mode", and at other times, and which comprises bursts of signals generated by generators 10A-10F, each operating at different frequencies, selected in predetermined combinations by means of a switching device 8 controlled by the "modechange" control device 7. The combined outputs of the generators 10A-10F are then undulated on to a sub-carrier frequency in device 11 the modulated wave from which is employed to modulate either the main vision carrier in transmitter 6 or the carrier for accompanying sound signals in the audio transmitter 15. At an authorized receiver (Fig. 2), the sub-carrier wave is derived from the audio channel 25 or from the video channel 26 and fed to a detector 27 in which the signals of 10A-10F (Fig. 1 ) are separately recovered and supplied to a like number of trigger circuits 28A-28F responsive to the frequency of respective ones of the generators 10A- 10F (Fig. 1) The combined outputs of the trigger circuits are then fed to a device 29 which responds to the combination of input signals thereto, (determined by the devices 7 and 8 Fig. 1), and supplies a control signal to a decoding device 30 to change the "mode" of the video signals supplied thereto from the video channel 26 in such manner as to compensate for the "mode" changes introduced at the transmitter and thus to allow the reproduction of a satisfactory picture by the picture tube 33. To improve the secrecy of the system the devices 7 and 8 (Fig. 1) initiate, in addition to "mode" change signals, further signals which do not change the "mode" of the transmitted signals and the device 29 (Fig. 2) is arranged not to respond to combinations of transmitted control signals which occur during such periods.

Abstract: 342,693. Speedometers. ASKANIAWERKE AKT.-GES., VORM. CENTRALWERKSTATT, DESSAU UND BAMBERGFRIEDENAU, 87, Kaiserallee, Friedenau, Berlin. Nov. 1, 1929, No. 33332. Convention date, Jan. 29. [Class 106 (iii).] The revolving shaft 1, the speed of revolution of which is to be measured, has fixed to it the casing 2 divided into two parts by the partition 2a, in one part 2c of which the piston 10 is reciprocated through the piston rod 11 engaging with the pin 12 fixed eccentrically to the fixed bearing sleeve 16. Air drawn in through the opening 17 is thus compressed in the space 2c and passes to the centre portion of the casing 2 through the pipe 6. In the other part 2b of the casing a piston 7 is movable under the action of opposed forces, namely, the pressure of the compressed air transferred from the centre portion of the casing 2 to the space 2b through the pipe 5, and the centrifugal force caused by the revolution of the shaft 1. The compressed air in the space 2b adjusts itself by escaping through the openings 15 the piston 7 taking up a position in relation thereto such that the centrifugal force on it is balanced by the force on it due to the air pressure. The speed of revolution of the shaft 1 is read off on a gauge 14. The lessened air pressure produced on the under side of the piston 7 on its movement outward acts as a pneumatic brake on the piston and loss of efficiency of this brake due to leakage of air around the walls of the piston is prevented by offsetting the central part of the piston 7 and providing openings 18 in the cylinder walls. In modifications, air may be replaced by any gas or liquid, the casing 2 may be arranged obliquely to the shaft 1, several pistons 10 may be provided and the pistons 7 and 10 need not be arranged in the same casing.

Filed: 1958-10-20
Abstract: 877,496. Automatic current control systems; automatic regulation. GENERAL ELECTRIC CO., Ltd. Oct. 20, 1959 [Oct. 20, 1958], No. 33453/58. Class 38 (4). In an automatic current regulator the direct current through a load connected to terminals 5, 9 from a source connected to terminals 4, 8 is maintained substantially constant by controlling the base current of a PNP germanium junction transistor 1 by the potential drop across resistors 2, 3 carrying the load current. The base electrode of the transistor is connected to the junction of a Zener diode 6 and a resistor 7, connected in series across the source terminals so that the constant voltage across the Zener diode tends to bias the emitter-base layer of the transistor towards a low-impedance. Variation in load current causes a change in the potential drop across the resistors 2, 3, biasing the transistor 1 so as to tend to maintain the load current constant. The Zener diode 6 and resistor 7 may be replaced by a constant voltage source connected between terminal 4 and the base of the transistor, the load and source terminals then being interchangeable.
